I know this an old thread but this fix also worked for me for the same problem (keyboard and other usb devices not recognized). Copying usb.inf to the \Windows\inf folder fixed it right up. THANKS!

Hi,
I copied the

Code:

usb.inf

from

Code:

c:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral_269d7150439b3372\

to

Code:

c:\Windows\inf\

and searched in the device manager for new devices.

And without restart or someting else, all USB keyboards are detected and windows installed the drivers.

Hi Ralf,

Yes, it's an old thread but still applies so I just wanted to say thanks for sharing the solution. I was going crazy with this problem for several days with ALL my USB based keyboards. I have just copied the usb.inf file and now all the keyboards are working. So, thanks a lot!

I know this is an old post, however, it comes up in google search so I shall provide my simple fix for correcting my simular issues with my keyboard not working. My issue came from a system crash, and 2 power failures. My keyboard would work fine until Windows loaded. I searched and tried every single "fix" I could find included all of them in this post with no luck.

A day later I finally just stopped looking for a fix and decided I'd be better off just messing around and solving it myself, the worst I could do would be trash my system...

So anyway, what I did to fix this was do what is in the post directly above me (which didn't work - but it was a step I took and may have influenced the fix to work), then I went to Device Manager where I had 3 HID Compliant keyboard drivers marked with an exclamation point.
I right clicked each one, selected "Update driver software...", then browse my computer, then selected "let me pick from a list...".
In the list were two drivers: HID Keyboard Device, HID-compliant device
Rather then selecting the driver that was not working I selected HID-compliant device.
I did that for all the bad HID drivers.
I then unplugged my keyboard and plugged it into another USB part, and viola, the proper driver installed. I then plugged the Keyboard back into the USB slot it was in before, but because I had changed this USB slots profile to use the improper driver I had to open up "Human Interface Devices" and uninstalled all the HID-compliant device drivers.
After that was done, I selected to scan for hardware changes in the Device Manager. Device Manager found and installed all the drivers properly and everything works perfect now.

Hope this helps because God knows I was very frustrated with this issue.

How do you delete your "PCI Bus" driver in device manager??

I had a similar problem with keyboard. It stopped working after Windows hibernated. After waking up keyboard was no longer working.

Although I did not install anything recently first I tried System Restore to a point a couple of days old, which was made by Microsoft Security Essentials Definition update. After finishing restore Windows booted and I logged in. Keyboard was working. But in a minute or so Windows displayed bubble in a system tray that "Device is now ready to work" and keyboard became dead again.

Not knowing what to do I rebooted Windows several time, looked for help online and found this page. usb.inf copy did not help. As guys here were posting about manual driver selection for their keyboard, I tried to do so myself. However Windows did not give me a choice of manual driver selection. Instead I chose "Browse my computer for driver software" and selected "C:\Windows\inf" as location to search for driver software. And it finally picked up keyboard driver and keyboard started working again.

However after disconnecting keyboard and connecting back it went dead again. And it was possible to fix this in an aforementioned way. Curiosity for "C:\Windows\inf" led me too google again and it directed me to this Microsoft page - Configure Windows to Search Additional Folders for Device Drivers.

In that page I found registry key HKEY_LOCAL_MACHINE/Software/Microsoft/Windows/Current Version\DevicePath. I checked it. It contained "%systemroot%\inf" as cautioned by Microsoft and a bunch of entries made by something like "Samsung USB Driver" installation. I uninstalled Samsung drivers and it removed its entries from DevicePath. And voila - keyboard is working each time I plug it out and back in...

Thanks Ralf

this also worked for me. I bought a new keyboard and it was not working on my windows 7. I copied the usb.inf to the c:\windows\inf and everything started working seamlessly.

Hi,

i know its an old thread, but when I searched for my same problem, I always got this links from Goggle.


Because I solved this problem on my PC (Windows 7 pro 64 bit) I want to tell my solution.


I had the problem with a new Logitech G510 keyboard. And after several other tries, suddenly, my Microsoft Keyboaard had the same problem. All other USB devices worked properly.

So tried the solution from
Troubleshooting für USB-Sticks unter Windows XP

I copied the

Code:

usb.inf

from

Code:

c:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral_269d7150439b3372\

to

Code:

c:\Windows\inf\

and searched in the device manager for new devices.

And without restart or someting else, all USB keyboards are detected and windows installed the drivers.

Perhaps you must search for another directory name

Code:

c:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral_269d7150439b3372\

Trie the newer one with

Code:

c:\Windows\System32\DriverStore\FileRepository\usb.inf_amd64_neutral....

Best regards
Ralf
